Abstract
Correction for ‘A truly bio-based benzoxazine derived from three natural reactants obtained under environmentally friendly conditions and its polymer properties’ by Irlaine Machado et al., Green Chem., 2021, 23, 4051–4064, DOI: 10.1039/D1GC00951F.
In the originally published manuscript, 10.1039/D1GC00951F, the Introduction contains the sentence ‘Only synthetically obtained paraformaldehyde and formaldehyde have been used as an aldehyde component for benzoxazine synthesis’. This sentence was unclear in that it referred to bio-based benzoxazines synthesised with the phenolic derivative, primary amine and aldehyde being able to be obtained from renewable sources. Benzoxazines that are not using renewable sources for these components have been synthesised before with other aldehydes, such as benzaldehyde1–3 and valeraldehyde.3
In the Methods section, the benzaldehyde was erroneously listed as being purchased from TCI, which does not sell naturally derived benzaldehyde. The authors have clarified that the benzaldehyde used was the naturally derived benzaldehyde purchased from Sigma-Aldrich.
The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
